I thought I'd post a final update:
So these files I couldn't delete were corrupt indexing files I had to delete from my Time Capsule because they were causing it to freeze up. It's a process I've done many times with no issue. The problem was I could not delete them from my trash bin and I couldn't use the "empty trash" function. I'd have to manually dump everything else in my trash. I tried every troubleshooting solution I could find with no results.
I then noticed that these files only showed up in the trash when my Macbook was connected to the Time Capsule. When I wasn't, they disappeared and the "empty trash" functionality restored. So I decided the best option was to erase the Time Capsule, not a big issue because the darn thing never worked right and every 90 days would tell me there was a problem with my old data and needed to do a new complete backup (it was a gift, bought as one of those holiday door dash specials years ago).
Wouldn't you now after I reset the darn thing I no longer have any issues. I have since decided to just not bother with it and buy an external drive to manually back up my data in one place (I have a gazillion flash drives with the same data too, I like redundancies). But in conclusion it was a buggy time capsule needing to be erased and reset.
